Call reservations, look at options through DEN, PHX, MIA, MCO, CLT, EWR, PHL, etc... cannot book second leg as US Airways and UA deny ticket transfer.

8:00
Still no options after nearly an hour of searching... Decide to check in person if UA/US can release seats on the second leg.

8:10
US Airways says they have room on a YYZ-CLT-AUS and even print out the flight number / availability

Call reservations... everything apparently switched
8:15
Check in at US Airways but told I need to go to AC and get a flight coupon number

8:20
Back at AC SE check in... "What does US Airways mean...?" A few calls back and forth
